Title: Improvements in Means for Automatically Controlling the Steering Mechanism of Marine or Air Ships.
Inventor: AGUIRRE ANGEL
IPC: B63H25/04
Filed: 1919-06-18
Abstract: 137,010. Aguirre, A. June 18, 1919. Steering.-Relates to means for automatically controlling the steering-gear of marine or airships by means of a magnetic or gyroscopic compass. The gimbal ring a, Fig. 1, is formed with arms a' which support the pivot stem b of a compass needle c enclosed in a bowl d. The bowl is mounted on ball bearings e in a channel a<2> and is covered with a transparent cover d<1>. The compass needle carries an insulated finger f which is adapted to engage with the contacts g, g. Figs. 3 and 4 show a plan and an elevation respectively of the contacts. The rods g, g are mounted on blocks h, h which may be moved towards or from one another by a right and left handed screw h<3> operated by bevel-wheels h<2> and spindle h<1>. The rods g may slide relatively to the blocks h in opposition to helical springs threaded on rods i. Each pair of rods g is included in the circuit of an electro-motor which is rotated in one direction or the other according to which pair is in contact with the member f, and the screwed spindle ? is correspondingly rotated. Rotation of the spindle j traverses the nut k, which thereby brings the contact k<1> into engagement with one or other of a pair of spring contacts l. The two pairs of contacts l are in circuit with two electro-motors which are adapted to rotate a pair of shafts m, Fig. 6, in opposite directions. Each shaft m has a pinion m<1> gearing with a pinion n<1> on a countershaft n. An axially-sliding sleeve o mounted on the shaft n carries three spur-wheels o<1>, o<2>, o<3>, which may be selectively placed in gear with the pinions p<1>, p<2>, p<3>, to rotate the shaft p at the desired speed. The end of the shaft p is screw-threaded and carries a nut r which is moved axially by the rotation of the shaft into contact with a clutch disk s<1> on the shaft s. A sprocket-wheel t is mounted on the shaft s and is connected to the spindle of the steering-wheel by a chain. The chain is not endless but has two free ends which carry weights normally resting on a flat surface. The steering-wheel is operated in one direction or the other according to which shaft m is actuated, and at the same time one of the weights is raised. When the motor ceases to operate, the weight brings the steering-wheel and consequently the rudder back to the mid-position. On the rotation of the spindle i, Fig. 1, the drum j<1> winds up a cord j<2> and lifts a weight j<3>. When the operating- motor stops owing to the contact f leaving the members g, the weight j<3> returns the spindle i' back to its mid-position and breaks the contact of the spring contact l. The central rods i are connected to the nut k by a pair of cords y, so that, as the nut is displaced, axially, the gap between the pairs of contacts g, g increases and contact with the member f is broken without the completion of the contact between the members k<1>, l and the starting of the steering-mechanism, when the deviation of the vessel is only slight.

Filed: 1942-11-02
Abstract: 561,845. Copying in colour by scanning. KODAK, Ltd. Nov. 2, 1942, No. 15373. Convention date, Nov. 1, 1941. Drawings to Specification.. [Class 40 (iii)] In the electro-optical reproduction of multicoloured originals, colour correction is obtained by producing in separate channels electric currents corresponding to the colour to be corrected and to the correcting colour, so amplifying these currents that their intensities become logarithmically proportional to the transmissions or reflectivities of the respective colours raised to exponentials whose ratio is the masking factor, scanning by light a photosensitive surface of the toe-emulsion type, and modulating such light in accordance with the linear difference between the intensities of the two currents. This difference may be obtained electrically or by the use of a light valve with a pair of electrically independent parallel ribbons in the manner described in Specification 561,844. Specifications 488,835, 516,816, 538,012, 538,013, 547,519, 547,734 and 552,367 also are referred to.

Title: Improvements in or relating to plumblines for use in mine shafts
IPC: G01C15/10
Filed: 1926-06-19
Abstract: 272,045. Wilson, W. H. June 19, 1926. Plumb-rules.-A device for locating a plumbline, particularly for use in a mine shaft, in the true vertical position and fixing it when so located comprises a plate a having a central aperture k through which the line m passes, and provided with four lugs b, c, d, f the axes of which extend over two diameters of the plate at right angles to each other. The lugs b, c extend vertically to a greater distance than the lugs d, f, and each lug carries a micrometer g having at its inner end a disc h. With the line oscillating about the vertical the micrometers are adjusted until it just touches the discs at the ends of its swing. The mean reading of each opposite pair of micrometers is then taken and by turning the heads to move the discs h through these mean distances the line becomes clamped between the discs in a truely vertical position. To indicate contact between the wire and the discs, such contact may be caused to complete the circuit of a lamp n or other indicator. The plate a is supported by levelling-screws on a lower plate i, preferably triangular.

Title: Improvements relating to the Preparation of Benzene-monosulphonic Acid.
Filed: 1916-11-07
Abstract: 126,039. Compagnie des Produits Chimiques d'Alais et de la Camargue. Nov. 7, 1916. Addition tn 101,973, Benzene monosulphonic acid.-In the production of benzene monosulphonic acid as described in the parent Specification, the benzene vapours are passed through a superheater before entering the sulphonater. Using the apparatus shown in Fig. 1, the benzene vapours from boiler A pass through a superheater B and then to a sulphonater C; the benzene vapour and steam passing off are condensed in the coil E and are separated in the decanter F; a tower G containing quicklime, calcium chloride, &c. dries the benzene which then returns to the boiler; fresh benzene is added as required from the vessel H. Fig. 2 shows apparatus for carrying out the process in a continuous manner; the sulphonater C is constantly supplied with sulphuric acid by pipe M from vessel D and the sulphonated product flows away by the pipe N. Several continuous treatment apparatus may be arranged in series with a common benzene boiler, the first sulphonater only being fed with sulphuric acid and delivering its sulphonated product to the next sulphonater and so on; this arrangement permits more complete utilization of the sulphuric acid.

Title: Method for forming thin oxide films
IPC: C01F7/02
Filed: 1963-04-23
Abstract: A substrate is coated with a film comprising a mixture of silica and alumina by exposing to substrate to a flowing gaseous mixture of vapour phase water, aluminium halide and silicon halide.  The halides are preferably the chlorides and the reaction is preferably carried out between the temperatures of 20 DEG  and 200 DEG C. The reaction is said to proceed by the hydrolysis of the halide vapours by the water vapour absorbed at the substrate surface, this concentration of water vapour ensuring that the reaction occurs at the surface and not in the gas stream.  The necessary heat for the reaction may be supplied by heating the reactant gases or the substrate.  An apparatus suitable for performing the process (Fig. 1, not shown), is described.

Title: Thermionic valve circuits
IPC: H04B1/22
Filed: 1923-06-20
Abstract: 223,625. Lodge, Sir O. J., and Robinson, E. E. June 20, 1923. Thermionic amplifiers and detectors.-A feeble alternating potential is worked up to a stronger alternating potential of the same frequency by the use of a low-resistance resonating circuit, capable of precise, tuning and having only a single connection with the conductor in which the feeble alternations occur. This circuit is uncoupled or only coupled so that the output takes so small a current as not to interfere with its free oscillation. In the circuit shown, a single connection only is made from a receiving circuit 15 to the low-resistance resonating circuit 17 connected across a thermionic value 16. A similar connection is also shown between the output of the valve 16 and the input of valve 20 in the form of the low-resistance resonating circuit 18 which is transformer coupled to the valve 20. In a modification, the receiving circuit is, on one side, directly connected to either the grid or filament of a valve, and, on the other side, is connected to the low-resistance resonating circuit, which is connected at the opposite point to the other input electrode of the valve. In a further modification, the low-resistance resonating circuit is joined directly to the grid of a valve and stimulated by joining an opposite point in the circuit to an aerial with no earth connection. The resonating circuit may also be connected across a crystal detector. One of the Provisional Specifications describes an arrangement to amplify the effect of the resonating circuit, in which the resonating circuit is connected to the grid of an auxiliary valve, the filament of which is joined to the source of oscillations while the plate is joined through a battery to the filament of the main amplifying valve. It also states that the inductance coil of the low-resistance circuit may be in relatively adjustable halves.

Abstract: 689,476. Conical grinding mills: BOLTON & SONS. Inc., J. W. June 28, 1950 [July 6 1949], No. 16135/50. Class 59 An apparatus for longitudinally adjusting the plug of a Jordan refiner of the type in which the forward and rear plug shaft bearings are slidable along a track comprises a housing mounted on the engine in extension of the track and including threaded means for advancing the rear bearing and spring means for exerting continual pressure on the said bearing and on the advancing means in the direction of backing off. In the plug adjustment means shown, rotation of a handwheel 51 causes, via interengagement of pusher and pushed plates 45, 46, respectively, longitudinal travel of a rod 52 which is connected to the casing of the slidable rear plug shaft bearing 12 of the refiner. Tolerance and play in the bearing and in the screwed handwheel connections are taken up by a spring S which is arranged to surround the rod 52 in a housing B, the end 57 of the spring abutting the end of the housing whilst the end 58 abuts a member 59 which is threadedly mounted on the rod. The housing B is mounted, by means of projecting flanges 41, 42, containing bolt-holes 43, 44, on an extension 30 which is welded to the main frame F of the refiner. The extension 30 is provided with flanges and these contain bolt-holes 33, 34, such that interengagement of bolt-holes 33, 34 with 43, 44, respectively, and the use of bolts 35 allows the initial affixing of B near the outer end of 30 and its subsequent removal and reinstallation nearer to the frame F as the refiner plug wears and the bearing casing 12 is caused to move to the left.
